2018 was an incredible year in every state and territory of mainland Australia.

There has never been a sustained boom of this magnitude occurring concurrently in every major state. Previous booms were the result of subsidy reductions at a federal or state level, and these booms typically lasted three months before going bust.

A cumulative >1 GW of STC systems installed in each of NSW, VIC, and WA

The chart below illustrates the peak months for the major states – with SA, VIC, and NSW all setting new record monthly volumes in November 2018, and WA setting its record volume in December. Only Queensland didn’t eclipse its monthly record, set in 2012… but it was only 2% off doing so.

The other major standout from the chart above is Victoria’s drastic leap in October 2018, which grew by 50% in a single month and absolutely smashed its previous record (set just months earlier) – clearly the result of successful state government policy.

As mentioned before, 2018’s success didn’t rely upon the success of any individual state, but was instead the result of record volumes experienced in every state and territory other than Tasmania, as illustrated below.

This chart also reveals the magnitude of growth in New South Wales, Victoria, and South Australia – each of which grew by more than 60% year-on-year – NSW to the point that it overtook Queensland in the STC market for the first time since 2010.

2019 looks almost certain to exceed the records set in 2018. Rooftop PV continues to offer an unbeatable financial return, solar farms in construction exceed the capacity built to date, and state government programs are ramping up.
